- SPECIFICATION forming part of Letters Patent No. 501,735, dated July 18, 1893.

' Application iiled November 5, 1892. Serial No.1151,0'78. (No model.)

.To all whom it may concern.-

Beit known that I, HENRY IWI. SHEER, of Quincy, in the county of Adams and State of Illinois, have invented a new and Improved Incubator, of which the following is a full, clear, andvexact description.

The object of the invention is to provide a new and improved incubator, which is simple and durable in construction, arranged to properly heat the egg chamber and to supply the necessary amount of moisture to the eggs.

The invention consists of certain parts and details, and combinations of the same, as will be hereinafter described and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, 1n which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of the improvement. Fig. 2 is a transverse section of the same. Fig. 3 is a sectional plan View of the water heater. Fig. 4 is a plan view of the moisture pans; and Fig. 5 is an inverted plan View of the heat iiue.

The improved incubator is provided with a suitably-constructed casing A mounted on suitable legs and preferably provided with double sides, bottom and` top, as plainly shown in the drawings. The interior of the casing A is provided with transversely-extending cleats B forming rests for the crates O containing the eggs to be hatched.

In the center of the casing A is arranged a heat Hue D surrounded by an air supply pipe/D both connected with each other at their lower ends by a perforated bottom plainly shown in Figs. 1 and 5. A pivoted latch D2, held on the underside of the bottom of the casing A, serves to support the said heat flue and air pipe in position in the casing A, it being understood that the lower ends of the said iue and pipe extend through the bottom of the casing A, to the outside.

Into' the heat flue D extends the chimney E of a lamp E supported on a bracket F hinged to one of the legs supporting the casing A, the said bracket being supported near its free end by a rod F hooked on a screw I attached to the under side of the bottom of the casing A. To disengage the chimney E from the heating ilueD,thebracketFis pushed rearward sufficiently to admit the lamp to be lowered and so removed from the heating iiue D. The upper end ofthe air iiueD extends a short distance above the upper end of the heat flue D and opens into a hot air distributing liue D3, on the upper end oi' which is adapted to be seated a valve G held on a rod G', automatically controlled by a thermostatic bar I-I, arranged Within the casingAin the chamber containing the egg trays C above mentioned.

This thermostatic bar H forms part of a y thermostatic regulator more fully shown and described in detail in an application for Letters Patent of the United States, Serial No. 451,077, and filed under even date herewith, so that a further description and illustration 'of the same are not deemed necessary. It sufioes to say that when the heat increases in the casing A, the valve G is unseated to `permit the heat arising from the lamp E to pass upward and out ot' the distributing chamber D3 into the outlet D4 passing through the top of the casing A.

The valve G is seated on the end ot the chamber D3, as long as the temperature is normal within the casing A. From the distributin g chamber D3 lead pipes D5, which extend horizontally through the water heater I', so as to heat the water contained in the said water heater. The outer end of each of these pipes D5 is connected with a chimney tlueD6 extending through the respective end of the casingA to permit the airto escape to the outside.

The hot water heater I is provided with a tank supported in a horizontal position on suitable cleats within the casing A above the crates C carrying the eggs. The tankof the water heater is provided with two longitudinally extending partitions l2, each formed at its ends with angularly extending deflecting plates I3, as plainlyV shown in Fig. 3. The partitions I2, divide the tank into a central channel'J and two side channels J and .I2 connected with the said central channel .I at the ends of the detlecting plates I3 of the partitions I2, as will be readily understood by reference to Fig. 3. The side channels J and J2 are connected with the central channel J, near the heat distributing chamber D3 by means of transversely extending pipes J3 eX- tending under the said channels and leading into their respective bottoms, as will be read- Each ily understood by reference to Fig. 2. of the pipes Js is provided with a drain cup J4, to remove the water from the hot water` heater whenever desired. By reference t0 Fig. 3, it will be seen that the air outlet tlues D5 extend through the central channel J and the pipes J3 lead into the said central ychanne'l near the air distributing chamber D3.

Now, it will be seen that when the valve G is closed, and the lamp E burns, the heat emanating from the chimney E causes asuction 4 of air in the air pipe D so that heated air passes into its central distributing chamber D3, and from the latter through the pipes D5 to the chimney 1iue D6. The air in the distributing chamber D3, and the pipes D5 heats the water in the central channel J of the hot water heater I, so that the water liows from about the middle of the channel J'to the ends thereof, to finally pass along the detlecting plates I3 into the side channel Jand then toward .the center or middle of the tank to.

finally pass through the pipes J3, which deliver the water in a cool condition tothe central channel J at or near the hot water distributing chamber D3. As the water is heated to the highest degree, around the air distributing chamber D3, and returns near the same by the pipes J3 in a cooler condition, a circui lation of water within the tank is established, without the water passing to the outer air.

On opposite sides of the air inlet pipe D are arranged the water pans K partly open on the top to permit the water contained in the said pans to evaporate, so that the chamber from the outside by means of a short pipe L l extending through the bottom of the casing A directly opposite the pipe K. On the top or cover of each pan K is arranged a slide L located directly above the short pipe K to deiiect the air over the water contained in the respective pan K.'

Itis understood that the moist air passes out of the pans near the ends of the same, through openings or transverse slots formed in the fixed cover or top of the respective pan. A rod N connects the two slidings covers L with each other, so as to shift the latter to the desired position. The rod N is formed at one end with a handle adapted to be taken hold of by the operator, through one of the doors Each of the' pans K is O held in the said casing A. The egg chamber containing' the trays is providedY in the end walls of the casing A with` Ventilating channels P extending vertically and connecting at their upper ends, with longitudinally extending channels P leading to apertures D7 in the outlet pipe D4. A ringQ is held 1n `this outlet pipe D4 and is provided with apertures Q adapted to register with the apertures l)7 so as to regulate the out flow of the air from the egg chamber, through the channels P, P, and outlet pipe D4. A handle Q2 `is secured on the ring Q and extends above the pipe D4 so that the operator can conveniently shift the saidring for regulating the outlet of the air through the said channels P, P', as above described. Below each egg crate C, is held in the bottom of the casing A, a tray R, containing moistened sand, to draw in any foul air accumulating in the lower part of the casing A.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The combination with the casing and its hot water vessel provided 'with a verticalhot air flue D3 leading through it and having a valve controlled communication at its upper end with thev exterior of the casing, and the lateral branches leading through the water vessel from said Hue, of the imperforate pipe D', extending upwardly from an opening in the bottom of the casing to the lower end of the flue D3 and the pipe D, (for the lamp chimney) within and of less length than the pipe D to permit the annular air space between said two pipes D D to open into the lower end of flue D3, substantially as set forth.

2. An incubator comprising a hot air distributing chamber and flues leading therefrom,and a hot water heater formed with a horizontally disposed tank, having a central channel into which extends the said air distributing chamber and the said air flues,sidc channels connected at their ends with the central channel, return pipes connecting the said side channels with the said central channel at or near the said hot air distributing chamber, and a valve adapted to open and close the top of the said air distributing chamber, to regulate the amount of heat passing through the said air filles, substantially as shown and described.

3. The combination with the casing having cold air inlets, its central hot air pipe, and the water vessel having hot air lues communieating with said pipe, of the elongated moistening pan provided with a central Vertical opening to receive said hot air pipe therethrough, cold air pipes K and two connected slides L L over said pipes, substantially as set forth.
